Building Requirements

If you see illegal development in the floodplains please report the issue through our Request Tracker.

Building Requirements:

Reduce or avoid flood losses by building above the Base Flood Elevation.

What is Base Flood Elevation?

The Base Flood Elevation (BFE) is the elevation to which floodwater is anticipated to rise during the base flood. BFEs are shown on Flood Insurance Rate Maps and on the flood profiles. The BFE is the regulatory requirement for the elevation of structures. The relationship between the BFE and a structure's elevation determines the flood insurance premium

FEMA form: Elevation Certificate

Structures Below Base Flood Elevation:

Monroe County enforces Monroe County Land Development Code Chapter 122 - Floodplain Management. Structures built after December 31, 1974, must have the lowest floor elevated to or above the base flood elevation. The owner or purchaser of a structure with habitable space below the base flood elevation may be faced with significant unforeseen expenses.

Legally permitted enclosures below the base flood elevation are for building access, limited storage and parking only. Limited storage means storage of lawn mowers, rakes, wheelbarrows, and similar pieces of equipment that are normally stored outside. Limited storage does not apply to household furnishings, workbenches, freezers, refrigerators, or other items subject to damage if exposed to salt water. If you are purchasing a home with a finished enclosure below the base flood elevation, it may not be permitted construction and may be subject to enforcement proceedings.
